Burping scares a joke.

Burping is a common physiological phenomenon. As a good way to treat hiccups, fright, as a strong emotional stimulus, can spread to the subcutaneous center through the cortex and inhibit diaphragm spasm. Hiccup, commonly known as hiccup, refers to rapid intake and glottis opening and closing caused by short-term contraction of respiratory muscles such as diaphragm and intercostal muscle. In most cases, hiccups can be stopped without intervention.

The sound of hiccups is sharp and urgent, and the breath comes from the throat. Accompanied by trunk vibration and shoulder deafness. It is often awkward to burp several times in a row. They often occur suddenly, usually caused by visceral smooth muscle spasm, and occasionally. Mild hiccups can be stopped by taking a deep breath, swallowing food and holding your breath after sneezing.

Persistent hiccup refers to more than 48 hours in a row, and intractable hiccup refers to more than one month. The trigger of hiccup depends on receptor, afferent nerve, central nerve, efferent nerve and effector to form a complete reflex arc. Hiccup is related to the pressure changes of human nerve and blood system. For example, when eating, swallowing something dry is easy to cause hiccups, which is because the local pressure changes due to the slow swallowing speed of food. The cause of hiccups is also the body's own response to local pressure changes.

When people are frightened, frightened, nervous and excited, the sympathetic nerve is excited and secretes a lot of adrenaline at the same time, while the functions of sympathetic nerve and parasympathetic nerve are changing; Vagus nerve is parasympathetic nerve, so it can explain that when people are frightened, sudden fear and tension make sympathetic nerve excited, adrenaline is secreted in large quantities, and stress response is obvious. At the same time, it inhibits vagus nerve, reduces excitability, stimulates diaphragm, and stops spasm and hiccups caused by it.

Other factors in life can also cause snoring, such as drinking carbonated drinks and eating too fast. According to the principle of burping, you can stop drinking as long as you interrupt the septal nerve reflex. As a strong emotional stimulus, it can be transmitted to the subcutaneous center through the cortex to inhibit diaphragm spasm. The way to scare people can really stop drinking, suddenly jump in front of people who burp, or pat their backs when they are not paying attention.
